JOINT FOR SANITARY FIXTURES.

Specification of Letters Patent.

Patented Feb. 16, 1909.

Application filed. April 12, 1907. Serial No. 367,821.

{invented a new and use ul Joint for Sanitar F ixtures {of which thefollowing is a ful clear, and exact description, reference being hadmane accompanying drawings forming part oflthis specification, in whichFigure 1 is a bottom plan view of-a fixture and joint embodying myinvention; and Fig. 2 is a central vertical section on lines II II ofFig. 1. I My invention has relation. to joints for sanitary fixtures,such as closets, lavatories, tubs,-sinks, basins, etc.,- and is designedto provide a joint so constructed that in case of gas leakage, eachflush of the system will cause a leakage of water which will show on thefloor of the room and at once notify the fjanitor or other attendant ofthe existence of the leak.

My invention consists in a joint which extends in a downward and outwarddirection from the interior of the fixture, and which, in-case of a gasleakage, will form a path through which water will escape to the outsideof the fixture.

Referring to the accompanying drawings, in which I have shown oneembodiment of myinvention, the numeral 2 designates the crockery foot ofthe closet or other fixture which is secured to the floor-3 by means ofthe usual screw bolts 4. The bottom endot' the foot 2 is formed withaniinternal recess or chamber surrounding its central opening to receivea flange 5 of brass or other suitable metal, and whichissecured withinthe foot by a setting 6 of the'cement. This cement may be of anysuitable hard setting water proof character, such as a mixture oflitharge andglycerin. The adjacent surfaces of the flange 5 and of theinner wall of-the recessc or chamber .in the; crockery foot 2 which areseparated by the cement filling 6,

are of such contour that the space or opening in which the-cement isplaced has a general outward. and downward course-in all directionsleading to the joint between theffoot2 is more securely anchore and thefloor oriother support 3. These sur;-

faces are also preferably provided with'the shoulders 8 and 9 ofcomplementaryform,and which form means whereb the brass flange is alsopreferably 'rovided with a in lace. Such wall of the crockery foot forthe purpose of insuring the correct setting of the flange, so

as to make a proper joint all the way around.

1 1 is bottom flange into which is soldered the lead pipe or bend 12, apacking 13 of vulcabeston or other water proof material beinginsertedbetween said flange and the flange 5. Instead of the lead pipe 12, it isobvious that the connection may be made by means of a pipescrewsthreaded into the flange 11 in the usual manner.

The advantages of my invention result from the construction, whereby Iprovide a joint of such character that in case of gas leakage each flushof the system will also cause the leakage of water to thereby indicatethe presence of the gas leak. As ordinarily constructed, the joints willpermit the leakage of as while nevertheless the water will be carriedpast the joint into the sewer, so that no indication of the leak isgiven. 'A further advantage of my invention results from the fact thatthe metal flanges of the fixtures are secured without auxiliary bolts orgrooves, and from the facility with which .L connection may be made withthe sewer,

from the'spirit and scope of my invention,

since What I claim is:-' 1. A joint adapted to connect a sanitaryfixture to a base'located upon asupporting surface and having its innerface exposed to-Water which passes through the fixture andzarrang'ed toindicate leakage on the passage of water through the joint.

2; A joint adapted to connect a sanitary fixture to a base located upona supporting surface and having its inner face exposed to I water, saldoint having substantially a continuous inclination downward and outwardfrom said face whereby a gas leakage will also occasion a water leakage.

3. A sanitary fixture adapted to be con nected with a base by a joint,said base being fastenedto a supporting surface-, said joint,-

having an inner face exposed to the water passing through the fixtureand forming. a downwardly inclined passage to indicate leakage throughthe joint upon the wall or 4. Asanitary fixturehaving a water passageand provided'i-n one end with an annular' recess'having itswalls-continuously inclined downwardly and outwardly from the waterpassage and free from upward passes, a metal flangevseated inandconforming to the configuration of the recess, and a layer of cementanchoring the flange in the recess and spacing the flange from the wallsthereof, substantially as described. '5. A sanitary fixture having awater passage and provided in one end with an an- "nular recess havingits walls continuously inclined downwardly and outwardly from the waterpassage and free from upward passes, a metal flange" seated in and con-'passes, a.metal flange seated in an 'formingto; the configuration of therecess,

a layer of cement anchoring t e'flange in therecess and spacing the flane from'the Walls thereof, another flange fitting the firstmentionedflange and formed-for connection said flange having spacing lugsengaging the walls .of the recess, and. a layer of cement scribed, s r8. A sanitary fixture; having a water pasannular recess, the wall ofwhich is stepped anchoring th'e flange in the recess and spacing saidflange from the walls thereof, substantlally as described.

7.'A sanitary fixture having a water passage, and provided in oneendwith an annular recess, ametal flange fitted in and conforming to theconfiguration of the recess,

said flange being spaced from-the walls of the recess and the annularspace formed wardly and outwardly from the water passage and freefronrupward passes, and cement filling said space and anchoring theflange in the recess, substantially as desage and provided in its lower"end 'with'an and continuously inclined downwardly and and spaced fromthe (walls thereof, cement' filling the annular space between the flangeflange the r ein, I another metallic flange fitting the bottom of thefirst mentioned flange and. formed-for connection with an "outlet pipe,packing between'the two flanges, andfastenings piercingthefixture andthe two flanges, substantially as described.

In testimony whereof, I have hereunto set my hand.
